Composting Greens and Browns: The Exact 25–30:1 Carbon-Nitrogen Ratio

Composting greens and browns is not a vague rule of thumb—it is a precise biochemical process governed by the carbon-to-nitrogen (C:N) ratio, and the optimal range for rapid, odor-free, pathogen-reducing thermophilic composting is 25:1 to 30:1 by dry weight. Deviating…
